Chapter 2. Installing options

This chapter provides detailed instructions for installing hardware options in the server.

Installation guidelines

Before you begin installing options in the server, read the following information:

v For a list of supported options for the server, go to

http://www.ibm.com/servers/eserver/severproven/compat/us/.

v Read the safety information beginning on page v and the guidelines in “Handling

static-sensitive devices” on page 12. This information will help you work safely with the server and options.

v Make sure that you have an adequate number of properly grounded electrical

outlets for the server, monitor, and other devices.

v Back up all important data before you make changes to disk drives.

v Have a small flat-blade screwdriver available.

v Yo u do not have to turn off the server to install or replace hot-swap power

supplies, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices.

v Blue on a component indicates touch points, where you can grip the component

to remove it from or install it in the server, open or close a latch, and so on.

v Orange on a component or an orange label on or near a component indicates

that the component can be hot-swapped, which means that if the server and operating system support hot-swap capability, you can remove or install the component while the server is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.

v When you need to access the inside of the server, you might find it easier to lay

the server on its side.

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that:

v Each of the drive bays has a drive or a filler panel and electromagnetic

compatibility (EMC) shield installed in it.

v There is adequate space around the server to allow the server cooling system to

work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place objects in front of the fans. For proper cooling and airflow, replace the left-side cover before turning on the server. Operating the server for extended periods of time (more than 30 minutes) with the left-side cover removed might damage server components.

v Yo u have followed the cabling instructions that come with optional adapters.

v Yo u have replaced a failed fan within 48 hours.

v Yo u have replaced a hot-swap drive within 2 minutes of removal.

v Yo u do not remove the air baffle while the server is running. Operating the server

without the air baffle might cause the microprocessor to overheat.

v Microprocessor socket 2 always contains either a microprocessor baffle or a

microprocessor and heat sink.

Working inside the server with the power on

The server supports hot-swap devices and is designed to operate safely while it is turned on and the cover is removed. Follow these guidelines when you work inside a server that is turned on:

v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts

before working inside the server; do not wear cuff links while you are working inside the server.

v Do not allow your necktie or scarf to hang inside the server.

v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist

watches.

v Remove items from your shirt pocket, such as pens and pencils, that could fall

into the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,

into the server.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices, including the server.

To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of damage from electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or its frame.

v Do not touch solder joints, pins, or exposed circuitry.

v Do not leave the device where others can handle and damage it.

v While the device is still in its static-protective package, touch it to an unpainted

metal part of the server for at least 2 seconds. This drains static electricity from the package and from your body.

v Remove the device from its package and install it directly into the server without

setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on the server cover or on a metal surface.

v Take additional care when handling devices during cold weather. Heating reduces

indoor humidity and increases static electricity.

Server power features

When the server is connected to an ac power source but is not turned on, the operating system does not run, and all core logic except for the service processor is shut down; however, the server can respond to requests from the service processor (also called the baseboard management controller), such as a remote request to turn on the server. The power-on LED flashes to indicate that the server is connected to ac power but is not turned on.

Turning on the server

Approximately 20 seconds after the server is connected to ac power, the power-control button becomes active, one or more fans might start running, and you can turn on the server and start the operating system by pressing the power-control button.

12 IBM xSeries 236 Type 8841: Option Installation Guide

The server can also be turned on in any of the following ways:

v If a power failure occurs while the server is turned on, the server will restart

automatically when power is restored.

v If the server is connected to an Advanced System Management interconnect

network that contains at least one server with an optional Remote Supervisor Adapter II SlimLine installed, the server can be turned on from the Remote Supervisor Adapter II SlimLine user interface.

v If your operating system supports the systems-management software for an

optional Remote Supervisor Adapter II SlimLine, the systems-management software can turn on the server.

v If your operating system supports the Wake on LAN

feature can turn on the server.

When 4 GB or more of memory (physical or logical) is installed, some

Note:

memory is reserved for various system resources and is unavailable to the operating system. The amount of memory that is reserved for system resources depends on the operating system, the configuration of the server, and the configured PCI options.

Turning off the server

When you turn off the server and leave it connected to ac power, the server can respond to requests from the service processor, such as a remote request to turn on the server. While the server remains connected to ac power, one or more fans might continue to run. To remove all power from the server, you must disconnect it from the power source.

feature, the Wake on LAN

Some operating systems require an orderly shutdown before you turn off the server. See your operating-system documentation for information about shutting down the operating system.

Statement 5:

The server can be turned off in any of the following ways:

v Yo u can turn off the server from the operating system, if your operating system

supports this feature. After an orderly shutdown of the operating system, the server will be turned off automatically.

Chapter 2. Installing options 13

v Yo u can press the power-control button to start an orderly shutdown of the

operating system and turn off the server, if your operating system supports this feature.

v If the operating system stops functioning, you can press and hold the

power-control button for more than 4 seconds to turn off the server.

v If the server is connected to an Advanced System Management interconnect

network that contains at least one server with an optional Remote Supervisor Adapter II SlimLine installed, the server can be turned off from the Remote Supervisor Adapter II SlimLine user interface.

v If an optional Remote Supervisor Adapter II SlimLine is installed in the server, the

server can be turned off from the Remote Supervisor Adapter II SlimLine user interface.

v If the Wake on LAN feature turned on the server, the Wake on LAN feature can

turn off the server.
